- This invention relates to nursing bottles landA the object of the .invention is to improve upon that type ci nursing `bottle having associated therewith means for-venting the bottle.

As is well known in the. art bottles of the last named type have been proposed for the purpose of permitting air to enter the bottle in a manner to cause an easy ow of liquid food from the bottle through the nursing nipple; to prevent the child from sucking air through the nipple; and to otherwise overcome various diiilculties attendant to the use of nursing bottles not otherwise equipped'. f,

In accordance with the present invention, a nursingbottle of the type above mentioned is provided which will not only overcome the above mentioned dificulties but will insure positively against a collapseof the nursing nipple, and

e which will also provide against leakage of the liquid -food contents regardless of whether thebottle is in use or not.

The invention together with its numerous objects and advantages will be'best understood from a study of the following description, taken in connection with the accompanying drawing wherein:

Figure 1 is a longitudinal sectional' view through a nursing bottle embodying the features of the present invention. .f

Figure 2 is a bottom plan view thereof.- Referring to the drawing by' reference numerals it will be seen that 5 indicates generally a nursing bottle of conventional size and shape; the same being provided with the beaded neck 6 to yreceive the nursing nipple 7. f

f a vent opening 11 and formed integral with the bottom wall 10 is a neck 12 that extends from the f concave side of the Abottom wall 10 and terminates atits-free end a material distance inwardly from the open sidel of the concavity 9 so as not to interierewith the placing of the bottle in 'an uprightorperpendicular position relative to a table or similarsupport.

At its free end the neck 12 which is preferably formed of thersame material as the bottle 5, namely glassisprovided with anexternal bead 1` claim. (ci. 21S-'11) (13." For the free end of the neck 12 there is provided a hap 14, the same being formed df a suit#` able elastic material, preferably translucent rubber. In applying the cap 14 to the neck, the same is snapped over the bead 13 in a manner to se- 60 cure the cap on the neck. At the crown or closed end thereof the ca'p 14 is provided with a plurality, preferably three, of relatively `small apertures 15, and due to the resiliency "of the material from which the cap 14 is made these apertures 15 65 are normally closed, it being apparent, that when the cap 14, is in an unexpanded or contracted condition the material of the cap about the apertures 15 contracts. i

In actual practice, when the cap 14 is in its 70 inal position on the neck 12, the cap will be expanded in a manner to `expand the apertures 15 to permit the passage of air therethrough and into the bottle 5 as the contents are drawn from the bottleV thereby preventing collapse of the nursing 7 nipple '1.

when desired the btue 5 may be lmieu with service the cap 14 may be but partially applied to the neck 12 in a. manner not to expand the cap 80" suillciently for expanding the material of the cap about the openings 15 and thus positively preclude leakage of theliquid food contents when the bottle is in a vertical position. When the bottle is to be used the cap 14 may then be pushed oi otherwise manipulated to its final/position on the neck 12 to expand the openings 15 for venting purvof` the bottle, said concave-convex bottom wall being provided with a vent neck of relatively smaller diameter than, and concentric with the v lsaid usual nipple engaging outlet of the bottle;

said vent neck terminating at its free end inwardly of said recess and provided at said free end with an external bead, and a exible cap provided with a relatively fiat head and a skirt.

integral with the head, theskirt of the cap being engaged with the vent neck and contractible about the neck behind the bead, and cooperating tures therein that are normally closed by the,

inherent resiliency of the material of the cap when the latter is partially applied to the vent neck, and open for vent purposes upon a. complete application of the cap to said neck.
